Submit your answers with all your R code in a .pdf format (limit your file to 6 pages). Write commentary/conclusions for every exercise.


Complete the exercises using the following "answer framework" for each question:



  1. Exercise/question number

  2. R Code / libraries should be included (important chunks are highlighted)

  3. Code output (data frame, vector, chart)

  4. A chart/visual, if needed

  5. Your comment, conclusions and/or insight into the results.


If your code produces errors and you cannot find a fix, try to explain what this error means. Do not ignore errors!
